the other things you might be interested in:
1. A feature function can give a -infinity score. If it's weight is
positive, then the hypothesis is guaranteed to be pruned

https://github.com/moses-smt/mosesdecoder/commit/5ebb81a17af4008768f8fd93d7ad31442325f47c
2. There can be more than 3 Evaluate() functions in the framework. For
example, Evaluate-After-All-Rules-Have-Been-Loaded(),
Evaluate-After-All-Rules-Have-Been-Applied-But-Before-Search(). Fabienne
knows more about those

that's strange. I'm using ubuntu and it's working for me. You may hace to
look around on the internet for a fix.

the EMS will still run even when these errors occur, but it would be nice
to fix them and see the images
